A shoreline observation post is located on a cliff such that the observer is 250 feet above sea level. The observer spots a ship approaching the shore and the ship is traveling ot a constant speed. To input your angle measures in degrees, use the functions sind (5), cosd (5) and tand (5), insteod of $\sin (5),\cos (5)$ and tan (5). a. When the observer initially spots the ship, the angle of depression for the observer's vision is 5 degrees. At this point in time, how far is the ship from the shore? feet b. After watching the ship for 42 seconds, the angle of depression for the observer's vision is 16 degrees. At this point in time, how far is the ship from the shore? feet c. What is the ship's constant speed (in ft/sec)? $\mathrm{ft}/\sec$ d. If the ship continues traveling at this constant speed, how many seconds after the observer initially spotted the ship will the ship crash into the shore? sec
